. DRAIN r TRAP.

Application filed. April 21, 1926. Serial No. 103,490.

More particularly the invention relates to a drain trap for refrigerators.

It is an object of the invention to provide a new and improved trap which is readily installed and which is conveniently removable for cleansing purposes.

It is another object of the invention to provide such a trap which is adapted to support a refrigerator drain pipe and to hold it against lateral displacement.

Another object is to provide such a trap which may be manufactured at a low cost by casting, stamping etc.

While I have shown in the drawings and 'will herein describe fully, two embodiments of my invention, it is to be understood that various changes in construction may be made by one skilled in the art without departing from the scope or" the invention as expressed in the appended claims.

In Figure 1 of the accompanying drawings I have shown, in elevation, a view partly in section or" one form of my drain trap incorporated in the drainage line or" a refrigerator.

Fig. 2 is a vertical section of the drain trap taken on the line 2-2 of Fig. 3.

Fig. 3 is a plan view of the drain trap shown in Figs. 1 and 2.

Fig. 4 is a vertical section of a modified form taken on the line l-4 of Fig. 5.

Fig. 5 is a plan view of the form shown in Fig. at and is taken on the line 5-5 of Fig. 4-.

In general my invention comprises a two part construction, one part being a cupshaped bottom member and the other a top or cover element removably fitted on the cup. The cup member is provided with an outlet above the bottom thereof. The cover element includes a bell adapted to overlie the outlet in the cup :to form a water trap and means to support the bell from the rim of the cup.

In the embodiment illustrated in Figs. 1, 2 and 3, my invention comprises a bottom element 6 preferably in the form of a relatively shallow cup having a bottom 7 and a peripheral wall 8. An outwardly projecting annular flange 9 and an inwardly extending annular flange 10 define an opening 11 in the bot-tom 7 of the cup. The external flange 9 is adapted to fit snugly into a waste pipe 12 which is provided to conduct the drainage from the refrigerator. The internal flange 1.0 is

adapt-ed to retain a quantity of water 13 in the cup at all times and forms an outlet 14 from the cup above the bottom of the cup.

The cover element comprises a rim 15, and a bell 16 preferably formed integrally therewith. The rim is adapted to fit snugly inside the peripheral edge of the cup 6 and is provided with means to hold it adjacent thereto, such means being herein illustrated as an outwardly extending an-' nular flange 17. The position of the flange in relation to the rim 15 is such that when the rim is positioned on the cup, the flange 17 will be supported on the edge or lip of the cup 6 and the rim 15 will extend partially into the cup to prevent lateral displacement of the cover member.

The bell 16 is central of the rim 15 and is connected thereto by a plurality of radial webs 18. This bell comprises a downwardly extending annular wall 19 having a diameter substantially greater than that of the internal annular flange 10. The height of the wall 19 is such that when the flange 17 on the rim 15 is supported on the lip 20 of the cup 6 the wall 19 will extend downwardly into the cup below the upper edge of the flange 10 to overlie the outlet 1% and thereby form a water trap.

Adjoining each web 18 and upstanding from the top of the bell are prongs 21 and an inwardly projecting and also upstanding lug 22. Between adjacent prongs the top of the cap is beveled to form a downward and outwardly sloping surface leading into arouate drainage slots 23 which are formed between the cap 16 and the rim 15 intermediate the webs 18.

The prongs 2-1 are adapted to receive the end of a drain pipe 24 to prevent lateral dis placement thereof and the lugs 22 support the drain pipe in spaced relation from the top of the bell 16.

The modified form of the invention shown in Figs. 4 and 5 is generally of like construction to the form just described but has, in addition to the prongs 21 a ring 25 joining the tips of the prongs. This ring serves to guard more positively against the accidental disengagement of the pipe 24 from the drain trap.

The insertion of the drain trap into a drainage system such as illustrated in Figure 1 is readily accomplished. First the cup is positioned on the end of the waste pipe 12 with the flange 9 inserted within the pipe 12. The cover element is then placed on the cup e and the drain pipe A from the ice chamber of the refrigerator is positioned within the prongs 21 with the pipe resting on the lugs 22. Due to the construction of the drain trap the entire drainage ssysteni 15 substantially rigid against lateral displaremeat. but the trap may he readily removed, cleaned. and replaced. Obviously the trap may rest upon the floor as shown in Figure 'l or it may he inset so that it flush with the floor.

I claim as my invention:

1. A. drain trap coin n'ising, a two part construction having; in combination. a cup having an outlet above the bottom thereof, and a cover element supported solely on the lip of the cup, said cover element including a sealing bell, means upstanding froin the surface of said bell to space a drain pipe therefrom and a plurality of upstanding prongs adapted to engage said d 'ain pipe.

2-. A drain trap comprising, in combination with a cup element having an outlet ahorethe hottonl thereof. a unitary cover element comprising a bell overlying said outlet to form a water trap, means upstand: ing from said bell arranged to engage a drain pipe to prevent lateral displacen'ient thereof and to permit water to drain therefrom into said cup, a rim formed integrally with said hell adapted to it Within the cup adjacent the uppeedge thereof to prevent lateral displacenumt of the hell therefrom. and an annular flange extending outwardly of said rim and overlying the li of mid cup to support the hell thereon.

In testimony whereof, l have hereunto afiixed my signature.
